## Questions & Answers

**Q: if this tank comes recharged at 20 psi can I add air too it if needed? the watts I have now is recharged at 40 but is bad now**
A: Yes air can be added. There is a valve stem at the bottom of the tank. As I recall, I brought the pressure up to 40 lbs. I checked out their website to see what I use for my well pump switch that runs 40 to 60 lbs.

**Q: What is the connection size?**
A: The fitting connection is 3/4" NPT threads.

**Q: This tank will be used on an rv, do any of the tank suppliers offer either a wall mount or cradle type floor mount for the heavier tanks? thanks, ray**
A: Hi Ray, I purchased the same expansion tank, and mounted it on my wall. The bracket I used was called Hydro Claw, by storm king. Its not cheap at about $35 to $40, but it is a well made, heavy duty bracket. Very nice looking install. Even my plumber buddies are very impressed! Highly recomend. Good luck, and stay safe.
Jeff H.

**Q: Rv parks pressure varies. have my incoming pressure set at 40psi. but when using the pump, it comes on at 35psi, & off at 60psi. is this a fit 4 us?**
A: May be helpful, but the pump run pressure range of 15psi is probably normal
